Use this CSI 3 part SimpleSpecs™ master specification to specify manufactured roof hatches, either galvanized steel or aluminum, single or double leaf, in ladder, stair, or steep stair (ships ladder) configurations.
Hatches provide for roof access where a penthouse and standard door are not provided.
The current edition of the International Building Code (IBC) requires that ladder access hatches be a minimum of 16 square feet with a minimum opening dimension of 2 feet. It also requires that protective railings be installed where the hatch is located with 10 feet of the roof edge.
Current OSHA requirements state that ladders over 24 feet in length be provided with a personal fall protection system. Refer to SimpleSpecs™ Master Specification Section 05 50 00 – Metal Fabrications for ladders and fall protection equipment.
Ladder extensions provide assistance in exiting and entering ladder-access roof hatches.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
